In the field of search engine optimization, link building describes actions aimed at increasing the number and quality of inbound links to a webpage with the goal of increasing the search engine rankings of that page or website.

Search engine optimization (SEO) is the process of affecting the online visibility of a website or a web page in a web search engine's unpaid results—often referred to as "natural", "organic", or "earned" results.

In general, the earlier (or higher ranked on the search results page), and more frequently a website appears in the search results list, the more visitors it will receive from the search engine's users; these visitors can then be converted into customers.

SEO may target different kinds of search, including image search, video search, academic search, news search, and industry-specific vertical search engines.

SEO differs from local search engine optimization in that the latter is focused on optimizing a business' online presence so that its web pages will be displayed by search engines when a user enters a local search for its products or services.

The former instead is more focused on national or international searches.

In the context of the World Wide Web, a bookmark is a Uniform Resource Identifier (URI) that is stored for later retrieval in any of various storage formats.

All modern web browsers include bookmark features.

Bookmarks are called favorites or Internet shortcuts in Internet Explorer, and by virtue of that browser's large market share, these terms have been synonymous with bookmark since the first browser war.

Bookmarks are normally accessed through a menu in the user's web browser, and folders are commonly used for organization.

In addition to bookmarking methods within most browsers, many external applications offer bookmark management.
